Damas, an Anabaptist leader of Hoorn, Dutch province of North Holland, and a weaver by trade, was listed with Jacob van Campen and Cornelis wt den Briel as one of the most prominent Anabaptists by Reynier Brunt, attorney-general of the Court of Holland, in a letter dated 24 March 1535. Damas baptized a Thomas Thomasz at Monnikendam. He must also have been active in the province of Zeeland. According to Vos, the man called David van Hoorn in the Confession of Obbe Philips was actually Damas, "David" being merely a slip of the pen. If this is the case, Damas was one of the twelve apostles sent out by Jan Matthijsz van Haarlem to proclaim the imminent kingdom of God. After his activities of 1534-1535 to spread the revolutionary ideas of Münsterite Anabaptism he disappeared and nothing more is known about him.
